“Now that’s a long time for some people, but speaking for the FBI, that’s light speed, all right?” Special Agent in Charge Aaron Rouse said.

Rouse spoke with the Las Vegas Review-Journal during an extensive interview Wednesday at the FBI’s Las Vegas office.

He said reports from other agencies that responded to the mass shooting are being released at different times.

“Ours is focusing a large part on the why, OK? Which is what everybody wants to know,” Rouse said.

The question of motive has gone unanswered since the shooting nearly three months ago, which left 58 concertgoers dead and more than 500 injured. Just 10 days after the massacre, Clark County Sheriff Joe Lombardo was largely unpromising about whether a motive would ever be determined.

“We may never know,” he told the Review-Journal.

On Wednesday, Rouse said the FBI has interviewed upward of 400 people worldwide, each of whom had some sort of connection — big or small — to gunman [name redacted so as to not add fame to these idiots].

“As I sit here today, I believe that we are learning as much as we possibly can about why the subject did what they did,” Rouse said, adding that investigators, as well as “various psychological and sociological” experts, are working the case.

The idea of never knowing a motive is troubling to me.

Don’t get me wrong. I don’t expect the FBI to create miracles, and I definitely don’t want them to just make up a motive, but the idea that someone could create an attack of this magnitude and leave no trace of their motive behind? I’m sorry, but that’s just disturbing.

While it sounds like the FBI is doing what they can to figure out a motive, it’s still worrisome that there wasn’t something very clear, something laid out to explain just why he would kill almost 60 people and injure hundreds more. Why do something like that unless you’re making a statement, even a mentally unbalanced one?

I hope they can give us some definitive answer on why. It’s not because it’ll change anything, or because it’ll somehow make it easier to stop other attacks necessarily, but because it’s just too difficult to wrap my head around someone doing something like this for no reason. Even finding out the killer believed the concert-goers were all pod people would provide a level of comfort. I can understand crazy as hell.

That’s probably why most people want to know the motive. It’s not for any other reason than to understand that there was some reason, that the killer didn’t just pull this just because.

Here’s hoping the report comes out earlier than expected, just to settle our minds.
